Methods, it can be advantageous to make voltage peak away substantially from the circuit board, have structural detail to be protected.
It is described to be preferred embodiment distinguished by by the overvoltage protection, a kind of of the present invention, it is described
Virtual architecture element is ceramic capacitor.In general such structural detail is the highest on printed circuit board (PCB) in geometric aspects
Structural detail so that thus possess in the fabrication process it is a kind of it is with low cost, can for realize the overvoltage protection
Row scheme.
The discharge protector, one kind be advantageously improved scheme regulation, the virtual architecture element is a kind of resistance.
This structural detail is used, a type of structural detail is also provided, it has just existed in the fabrication process, and thus, it is possible to
Realize the overvoltage protection, a kind of with low cost and effective design.
It is described preferred embodiment to be provided by overvoltage protection, one kind of the present invention, the virtual architecture member
Part is contact pin.Thus a kind of embodiment party a kind of particularly simple and with low cost, for realizing the present invention is provided
The feasible program of formula.
Pass through the device by the present invention, it can be advantageous to so improve the safe class for the motor so that
The esd discharge process occurred in operation will not damage the motor, have element to be protected.It is possible thereby to advantageously significantly
Extend the motor, the trouble-free duration of operation.Advantageously, it is additional, described by mistake of the invention for providing
The expense very little of voltage protection.
With other feature and advantage, by means of two accompanying drawings, the present invention will be described in detail below.Here, all institutes
Describe or shown feature all forms subject of the present invention in itself or in arbitrary combination, and this point is not dependent on
The feature, general introduction in the claims or the adduction relationship to it, and be not dependent in the description or
Statement to it or diagram in accompanying drawing.The accompanying drawing is contemplated for first：Illustrate principle important for purposes of the invention, and
And not necessarily according to details or proportionally chi.Accompanying drawing is shown：
Fig. 1 is the front view by a kind of embodiment of overvoltage protection of the invention, principle；And
Fig. 2 is the top view by a kind of embodiment of overvoltage protection of the invention, principle.
Embodiment
Fig. 1 is shown described by the present invention, for motor, overvoltage protection one kind with the front view of principle
The schematic diagram of embodiment.May be from the motor, the axle 4 that can be rotated around rotation axis to cloth on the circuit card 1
Put the electric discharge arcing that electrostatic is carried out on below the axle 4, electric or electronics structural detail.Its reason such as exists
In, a kind of relatively thin oil film is produced on the axle 4 in the running of the motor, thus prevent and ground potential（Such as
Housing ground wire）Between, low-impedance conductive connection.In this way, the too high phenomenon of electric charge, institute are produced over time
The too high phenomenon of electric charge is stated in the discharge process of electrostatic（ESD sparks）Discharge into the sensor element 3 for being arranged in the lower section of axle 4
On, thus the sensor element is likely to be broken or damages.In the normal operation of the motor, the sensor element is used
3 detect angle position and/or the rotating speed of the axle 4 that the wiper to motor vehicle is driven.For this purpose, such as can be with
By a magnet（It is not shown）It is pressed on the axle 4.
Provided now according to the present invention, set one virtual on the circuit board 1 in the vicinity of the sensor element 3
Structural detail 2, the virtual architecture element is so constituted and is arranged on the circuit board 1 so that it is with other in described
Structural detail on circuit board 1, which is compared, has minimum spacing relative to the axle 4.Method in this way, can be with very
High possibility makes the arcing arcing of electrostatic to the virtual architecture element 2, thus described to have sensor element 3 to be protected
It will not be damaged or damage.Thus, provided according to the present invention, the virtual architecture element 2 has to be protected more than described
Structural detail, wherein the virtual architecture element 2 has more than described in, the degree of element to be protected is bigger, and protective effect is got over
It is high.
It is used as a kind of embodiment for the virtual architecture element 2, it is considered to a kind of ceramic capacitor, a kind of resistance, one
Plant contact pin etc..Protective effect is advantageously dependent only on the external dimensions of the geometry of the virtual architecture element 2, wherein
The virtual architecture element or pesudo-structure element 2 are not integrated into the operation of the function of the motor.Thus, it is described virtual
The advantageously a kind of component with low cost of structural detail 2, in general it be already present on the dress of the circuit board 1 of the motor
Standby inventory（Bestückungsliste）In and thus do not produce fringe cost.
Fig. 2 shows overvoltage protection 10, a kind of embodiment, principle the vertical view by the present invention
Figure.As can be seen that so connecting the virtual architecture element 2 on both sides by means of the electric wire 5 of the circuit board 1 so that institute
State electric wire 5 to draw from the virtual architecture element 2 on shorter circuit, or the circuit is routed in as short as possible
It is accomplished on plate 1.It is preferred that the electric wire 5 is applied on a kind of ground connection star convergence point, the ground connection star convergence point is collected
The discharge energy of the electrostatic, and exported by plated through hole to plug（It is not shown）, and thus by it from institute
State and drawn on circuit board 1.Method it can advantageously make harmful voltage peak away substantially from the electricity in this way
Road plate 1, function structural detail.The electric wire 5 should be preferably configured as structure as low-impedance as possible.
In a word, a kind of simple and effective feasible program is provided with the present invention, for protecting the circuit in motor
On plate, electronics structural detail or whole standard packages, to prevent the electric discharge of electrostatic.This point is advantageously by means of one kind
The physical dimension of virtual architecture element realizes that the virtual architecture element so constitutes so that its electric discharge in the motor
A kind of minimum spacing is provided between the terminal of circuit.Such as due to passing through the electrostatic caused by being scraped on dry glass
The ESD sparks for charging and producing can be in this way in the inside of wiper motor in most short and low-impedance circuit
On harmlessly guided.
For those skilled in the art, it can be seen that the principle by the present invention is not limited to have rotation
Axle motor, but can in a similar way apply on every kind of device, electrostatic is likely to occur for described device
Electric discharge, and/or ESD arresters defined in should producing for described device.Such as not must be by institute
Virtual architecture element is stated to be directly arranged on the circuit board.
Thus, described feature can be combined with each other or it is changed by those skilled in the art, and
Without departing from the core of the present invention.
